Martyn Rooney and David Greene confirmed their credentials as potential gold medallists at next month's European Championships with impressive displays at the weekend's trials in Birmingham.
Rooney produced a commanding victory in the 400 metres to book his place on the British team for Barcelona, clocking 44.99 seconds for the second time this season.
That is the joint fastest time by a European athlete and was the first time a British athlete has broken 45 seconds on home soil since he did it two years ago.
The 23-year-old from Croydon, who was sixth in the Olympics on his debut aged just 21, said: "I'm very happy. It was a nice enjoyable race and the first time this race has been competitive for a while.
"I ran well. I think there are bits of it that weren't amazing but I'm happy with the result. I definitely think (Michael) Bingham pushed me and I thought 'Oh here we go, we've got a race,' but I knew I was strong and I just had to do my job."
Bingham took second in 45.67secs to also seal his place in Barcelona, with Conrad Williams close behind in third.
Greene also came into the 400m hurdles ranked first in Europe and clocked a season's best of 48.77s at the Alexander Stadium.
"It's always good to defend your title and I ran faster this year than last year and it's a season best," Greene said. "It's pretty windy out there but it was a very good performance, I'm very pleased."
Fellow Welshman Rhys Williams, who won bronze at the European Championships in 2006 but has been plagued by injuries since, was second in 49.76s, again achieving the 'B' standard which should also see him selected.
In fact hurdles events could provide several medals in Barcelona, with the men's 110m hurdles producing the best race of the weekend, William Sharman edging out four-time champion Andy Turner by just 0.03s.
Sharman, who was a shock fourth at the World Championships in Berlin last year after being a late addition to the team, said: "Andy may have been second here but I still fancy him for the Europeans. I heard he was out for his fifth title and I just had to do something about that.
"But I do like the big stage so we will have to see. I think we are both among the top hurdlers in Europe but you have to bring your 'A' game on the day and anything less than that will cost you. One mistake and the race is over."
Elsewhere, Goldie Sayers won an unprecedented eighth straight title in the javelin, although the 27-year-old had to make do with a below-par best of 58.60m, while world champion Phillips Idowu won the triple jump with a best of 17.12m.
In the absence of world bronze medallist Jenny Meadows, who withdrew with a calf injury after winning her semi-final, Jemma Simpson won the women's 800m, while Michael Rimmer won his fifth title in a row with a commanding win in the men's event.
